[ I ] In the substitution nomenclature of alcohols and phenols, it is a suffix attached to the name of a hydrocarbon or basic heterocycle. An example is shown in the following figure.

The -ol is also found in commonly accepted names such as phenol and cresol. [ II ] In polynuclear complexes, when OH- acts as a bridging ligand, it was once called "ol", but this term is no longer used. Complexes with this bridging structure are also called "ol complexes". The following structural formula

was originally called octaammine-μ-diol-dichromium(III) salt, but is now called di-μ-hydroxo-bis(tetraamminechromium(III)) salt.
